Explore Kinematics — The Science of How Things Move

📖 The Basics

💡
Kinematics is the branch of physics that studies HOW things move — without asking why. Speed, velocity, acceleration — these are all kinematics!
🏃 Distance vs. Displacement
1
Distance = Total path traveled (scalar — just a number, no direction). Think of it as "how far you walked total."
2
Displacement = Straight-line from start to finish (vector — has direction). Think of it as "how far from where you started."
🏠 Walk from home → school (2 km) → back home (2 km)
Distance = 4 km  |  Displacement = 0 km (you're back where you started!)
⚡ Speed vs. Velocity
1
Speed = How fast (scalar). "I'm going 60 km/h"
2
Velocity = How fast AND in which direction (vector). "I'm going 60 km/h NORTH"
Speed = Distance ÷ Time   |   v = Δd / Δt
🚀 Acceleration

Acceleration is the rate at which velocity changes. When you push the gas pedal, you accelerate! When you brake, you decelerate (negative acceleration).

a = (v - u) / t
🔼 Positive a: Speeding up
🔽 Negative a: Slowing down
🎢
When a rollercoaster drops, you experience rapid acceleration from gravity! Your body feels heavy going up and almost weightless at the top. That's Newton's kinematics in action!
📐 The SUVAT Variables
S = Displacement (m)
U = Initial Velocity (m/s)
V = Final Velocity (m/s)
A = Acceleration (m/s²)
T = Time (seconds)

💡 Know any 3 variables? You can find the other 2 with SUVAT equations!

Missing: s
s = ut + ½at²
Missing: v
v² = u² + 2as
Missing: t
s = (u+v)/2 × t
Missing: a
s = vt - ½at²
Missing: u
🎯 SUVAT Strategy Guide
1
List what you know: Write down S, U, V, A, T values given in the problem.
2
Identify the unknown: What are you trying to find?
3
Pick the right equation: Choose the SUVAT formula that has your unknown and doesn't need the variable you're missing.
4
Plug in and solve! Substitute your values and calculate.
